What each the command to the girl mean?(Follow, Charge,...) Also is there any inventory system yet?
Basically, this is what each command does:
Follow: The girls will try to stay with the MC. They also do what he's doing as well. This is how you get them to drag stuff with you, pick up meat, dissect animals, get on or off the rover, load meat onto the rover or as energy, etc. If you do an action, they'll basically start doing it too (other than mating, which has to be by the Mc or enemies only)
Charge: The girls follow you, but are a lot more aggressive and will try to fight any enemies or animals in the area without question. great if you want to swarm enemies (setting everyone to aggressive) or even let a girl Leeroy Jenkins herself into getting KOed and raped (setting one girl to aggressive). They will also get right out of the rover and stay out if ANYTHING that's killable is nearby.
Vigilance: Haven't used it much, but this is like a mix of Follow and Charge. Don't know the full mechanics of it, but it does make it easier to mate someone while the rest fight the enemies nearby off of you (like if you're trying to get a girl to your side but there's still enemies left).
Return: This basically makes the girls drop everything and return to the base. If you have the Rover, they'll prioritize it first. Only exception is when the rover is inside the base boundary, where the girls will get off the rover instantly and stay at the base. This is good for dividing your forces up, or if you just want everyone to come back or get out of there for some reason.
Also, you can't give commands to KO'ed girls and they'll default back to follow. So if they're getting back up and you DON'T want to lose them (cause allies come back with almost no HP), you need to be quick on giving them another command (such as return).
There's also no inventory system cause there's no need for one. You're only picking up 2 kinds of meat (cooked meat heals you but is only dropped from natives). Other than that, you're attaching parts (and animals you didn't dissect for some reason) to the Rover. Any menu stuff like recharging the weapons and Rover is done back at the base and it all runs off the energy you gain from bringing back meat.
